Biological Survey Results Database of Water Areas
Last update date April 1, 2024
In the biota survey results of water bodies conducted almost every three years since 1973, we have created a database of fish and benthic animals in rivers, fish and coastal animals in sea areas, for each survey date, point, and confirmed species. We provide data on 4,268 river fish, 16,856 river benthic animals, 7,295 marine fish, and 12,869 coastal animals in Excel format.
If you wish to use this service, please be sure to read the Database Terms of Service.
